 * This is a slight variant of session_ip.

 * Session management scheme that uses the DNS name of the computer
 * to identify users and administrators.
 * Anyone who can access the server can make bookings etc.
 *
 * To use this authentication scheme set the following
 * things in config.inc.php:
 *
 * $auth["type"]    = "none";
 * $auth["session"] = "host";
 *
 * Then, you may configure admin users:
 *
 * $auth["admin"][] = "DNSname1";
 * $auth["admin"][] = "DNSname2";
